One option that is useful to change is the
``Terminal'' setting. This will be set correctly if all you want to do is
view the graphs on your screen with Gnuplot.
If you want to get a hardcopy
printout, you have two alternate choices for the ``Terminal'' option.
If you have a postscript printer, then use ``postscript'' as the terminal.
Run Preplot, and then run Gnuplot as explained in Section 4.3.
You will not see any output, but a file qtlcart.ps will be created
(or stem.ps, where ``stem'' is your filename stem). This file can
be sent to any postscript printer. The other alternative is ``hpljii'',
which does something similar for HP-LaserJet II's (the output file will
be stem.hp). You could use the ``hpljii'' option for ``Terminal'', and
then edit the stem.plt file to change the type of printer to anything
that Gnuplotsupports: See the Gnuplotmanual [Williams and KelleyWilliams and
Kelley1993]
for more details.
